Magnesium silicate ceramic material and preparation method thereof
The invention provides a magnesium silicate ceramic material and a preparation method thereof. The preparation method comprises the following steps: drying and crushing a raw material containing serpentine minerals to obtain first powder, or drying and crushing the raw material containing the serpentine minerals to obtain first powder, and roasting the first powder to obtain second powder; mixing the first powder and/or the second powder with ingredients to obtain mixed material powder; granulating the mixed material powder to obtain a spherical granular green body; and drying and sintering the spherical granular green body to obtain the magnesium silicate ceramic material. The magnesium silicate ceramic material comprises magnesium silicate ceramsite and/or magnesium silicate pottery sand, wherein the diameter of the magnesium silicate ceramsite is 5 to 30 mm, and the diameter of the magnesium silicate pottery sand is 150 [mu]m to 5 mm. The magnesium silicate ceramic material is produced by taking rock, waste rock and tailings which mainly contain serpentine as raw materials, so the resource utilization of various solid wastes is realized.
本发明提供了一种硅酸镁陶质材料及其制备方法。制备方法包括：将含蛇纹石矿物的原料进行干燥和破碎，得到第一粉体；或者，将含蛇纹石矿物的原料进行干燥和破碎，得到第一粉体，再将第一粉体进行焙烧，得到第二粉体；将第一粉体和/或第二粉体与配料进行混合，获得混合物料粉体；将混合物料粉体进行造粒，获得球形颗粒状坯体；将球形颗粒状坯体进行干燥和烧结，获得硅酸镁陶质材料。硅酸镁陶质材料包括硅酸镁陶粒和/或硅酸镁陶砂，硅酸镁陶粒的直径为5mm～30mm，硅酸镁陶砂的直径为150μm～5mm。本发明以主要含蛇纹石的岩石、废石、尾矿为原料生产硅酸镁陶质材料，实现了多种固体废物的资源化利用。
